System Design Options

Software deployment for the LeasePak server, Oracle Database, and Oracle Client can follow either a split system or unified system design.

Split System

On a split system, the LeasePak server and Oracle Client reside on one computer (the application host), while the Oracle Database resides on a separate computer (the DBMS host), with the two computers communicating over a network.

Application Host

Components of the application host are:
  • RHEL operating system (64-bit)
  • Oracle Client software (32-bit)
  • LeasePak server software (32-bit)

DBMS Host

Components of the DBMS host are:
  • RHEL operating system (64-bit)
  • Oracle Database software (64-bit)
  • Oracle physical database (database disk files)
  • Oracle instance (background processes and shared memory)

Unified System

On a unified system, the LeasePak server, Oracle Database, and Oracle Client reside together on the same computer (the combined host).

Combined Host

Components of the combined host are:
  • RHEL operating system (64-bit)
  • Oracle Database software (64-bit)
  • Oracle Client software (32-bit)
  • Oracle physical database (database disk files)
  • Oracle instance (background processes and shared memory)
  • LeasePak server software (32-bit)
The combined host functions as both the application host and DBMS host. For a unified system, when a reference is made in the LeasePak DBMS documentation to the application host or DBMS host, typically interpret it as a reference to the combined host. The documentation will explicitly state when a reference to the application host or DBMS host applies only to a split system host and not to the combined host of a unified system.
